I don’t usually write App Store reviews, but this app is awesome. I previously thought it was not possible to load .vtt subtitles into a .ts video file without converting the video to an MP4 file. Attempting to play a .ts file with an imported .vtt subtitle file would prompt a glitch the VLC app.
So, I installed this app based on the app description for subtitle support and was stunned at the performance. It not only did what i wanted, and EVEN more. I was able to easily customize my subtitles (i.e. font, size, color, background, etc.) that I was not able to on the VLC app. 5 stars, well deserved.
